My wife and I have had new windows and doors supplied by John and his excellent team over the last few days. The service has been exceptional from start to finish. John attended and gave a very competitive quote compare with 3 other local and national companies. No lengthy sales pitch or discounts if you sign up now, just honest and competitive quote with no pressure. The products were made and fitted within 3 weeks. They are of excellent quality. Darren and Adam the fitters were the most friendly and helpful tradesmen we have ever used. They are prompt, tidy and highly skilled professionals. We are so please as other trades people have often disappointed. Advanced Glazing Systems Ltd did not disappoint. Kind Regards Andy and Jan

John and the team were excellent from start to finish, simple as that. They were very keen to do what was best, not only our budget but also what would suit the features of our home. John came up with some great practical solutions for us which we'd previously not considered. I would definitely recommend AGS to anyone for price, quality of windows and installation.
